80649-01 | Bently Nevada TK81 Tunable Filter/Vibration Meter

Description

The TK81 Tunable Filter/Vibration Meter is a portable handheld instrument designed for basic vibration measurements. It can display vibration in both unfiltered (overall) and filtered modes. The meter accepts inputs from displacement, velocity, and acceleration transducers but does not supply power to them. The filtering feature is particularly useful for diagnosing vibration problems occurring at specific frequencies in machinery.
